* findvar.c (read_var_value): Remove case for thread local storage
variables. It is now entirely handled by the dwarf2 location
expression code.
* printcmd.c (address_info): Ditto.
* symtab.h (address_class): Remove LOC_THREAD_LOCAL_STATIC
enumeration value.
(struct symbol): Remove objfile field, which was used by
LOC_THREAD_LOCAL_STATIC only.
* dwarf2read.c (decode_locdesc): Remove is_thread_local variable.
* dwarf2loc.h (struct dwarf2_loclist_baton): Add comment about
usage of objfile pointer.
* dwarf2loc.c (locexpr_describe_location): Add case to handle
thread local variables.
Add include of objfiles.h.
* dwarf2expr.c (execute_stack_op): Add comments about thread local
storage variables.
* Makefile.in (dwarf2loc.o): Update dependencies.
